STOVEPIPE LOCK.

Application led December 23, 92. Serial IlTcfGDS T 0 all whomz't mayconcern.'

Be it kno-wn that I, BLANCHE LEACH, a citizen of the United States,residing at Reno, in the county of Washoe and State of Nevada, haveinvented new and useful lmprovements in Stovepipe Locks, of which theAfollowing is a specification.

rlhe object of this inventionis to produce an extremely simple, cheapand effective means for locking a stove pipe sectionA in a chimney.

A further object is to produce a loclr of this character constructedfrom a single piece of suitable wire or like metal, journaled inbearings in the groove at the seam of a stove pipe section and havingits ends disposed at such angles that one of the same will be brought toa position to permit of the ready insertion of the section through theopening therefor in the chimney breast and thereafter turned with theopposite end so that both of the ends will be brought to contactingengagement with the inner and outer faces of the wall of the chimneybreast.`

To the attainment of the foregoing, and other objects which will presentthemselves as the nature of the invention is better understood,reference is to be had to the drawing which accompanies and which formspart of this application.

In the drawing Figure l is a view showing the manner in which the stovepipe section provided with the improvement is inserted in the flueopening in a chimney breast.

Figure 2 is a Similar view showing the arrangement of the lock when thestove pipe section is fully inserted in the opening therefor.

Figure 3 is a sectional view on the line 3--3 of Figure l.

Figure l is a similar sectional view on the line 4 4: of Figure 2.

Figure 5 is a perspective view of the lock.

Referring now to the drawing in detail, the numeral l designates achimney, 2 the stove pipe opening which communicates with the flue ofthe chimney, and 3 a stove pipe section which is designed to be receivedin the opening 2.

The pipe section 3 is of the usual const-ruction, the pipe seam of whichis formed with a channel 4. Bridging the groove 4 are metal straps 5,the said straps being riveted or otherwise secured to the pipe section3.'

The channel and the plates 5 provide a bearing for the body or shaftportion 6 of my improved lock, The lock is preferably constructed ofsteel wire and the body or shaft 6 thereof has one of its ends bent at aright angle therefrom, as indicated by the numeral 7. The opposite endof the shaft 6 is also bent, but at an obtuse angle, as indicated by thenumeral 8. The portion 8 has its outer` end bent downwardly with respectto the journaled shaft 6 and right angularly with respect to the angleportion 8. The last mentioned portion is for distinction indicated bythe numeral 9, and forms what I will hereinafter refer to as the handleof the improvement.

By swinging the shaft 6 to the position illustrated in Figure l, theangle or finger end 'T of the shaft will be disposed downwardly or inthe direction of the bore of the stove pipe section 3. lfVhen the stovepipe section is fully inserted in the opening 2, the outer angle end ofthe shaft will contact with thel chimney 'l and the handle portion isgrasped to turn the shaft to the position illustrated in Figure 2, thusbringing the angle end or finger 7 upwardly into contacting engagementwith the inner wall of the chimney l. and the angle portion 8 as well asthe handle 9 into contact with the outer face of the chimney l.

It is thought that the foregoing description7 when taken in connectionwith the drawing will fully set forth the construction and advantages ofmy improvement to those skilled in the artto which this inventionrelates. lt is to be understood that the lock being constructed of steelwire embodies an inherent resiliency so 'that the linger end and thehandle end 8 and 9 may be bent in the direction of or away from theshaft or body. (i whereby a frictional engagement of the ends of theshaft with the inner andk outer faces of the chimney will be affordedeven when the shaft 6 is of a greater length than that of the opening 2.

Having described the invention, I claim The combination with a chimneyhaving a pipe opening and a pipe section to be received in said Vopeningwhich has its seam formed with a channel, of a means for locking thepipe section to the chimney, comprising a. shaft received in the grooveof the pipe section. plates straddling the shaft and secured to the pipesection, said shafthaving one end terminating with one end of the pipesection and arranged' at a right angle mit of the handle end of theshaft being brought into Contact with the outer fece of the chimney andthereafter 'further turned to bring both ends of the shaft intoco'ntacting engagement with the respective inner and outer faces of thechimney.

In testimony whereof I ailix my signature.

BLANCHE LEACH.
